How can I avoid right click event on a vtkSeedWidget / vtkSeedRepresentation ?  
I have tried:

```
	vtkSeedWidgetCallback* pCallback = vtkSeedWidgetCallback::New();
	pCallback->SetRepresentation(pSeedRepresentation);
	m_pSeed->AddObserver(vtkCommand::PlacePointEvent, pCallback);
	m_pSeed->AddObserver(vtkCommand::InteractionEvent, pCallback);
	m_pSeed->RemoveObserver(vtkCommand::RightButtonPressEvent);
	m_pSeed->RemoveObserver(vtkCommand::RightButtonReleaseEvent);

```

but on the right click is called vtkSeedWidget::CompleteInteraction wich stop the planting of seeds … I want to stop the user to give up planing seeds until the number of seeds is 5.
